I've recently noticed that some code is creating threads without  
standard initial bindings.  The most recent bordeaux-threads sources  
seem to do this in openmcl.lisp:

(defun %make-thread (function name)
   (ccl:process-run-function (list :name name :use-standard-initial- 
bindings nil)
                             function))

This is probably not a great idea...
